To a'ZZ whom z' may concern:

Be it known that we, NATiiANmL SIMON- new and useful Improvements in,RoadiVm-king Machines, ot' which Vthe following is a specification.

This invention relates to road working 4machines, and it hasparticularrel'erence to ythat class ot machines which. are provided withrearwardly convergent scraper bars Vspacedapart at their rear ends topermit the passage therebetween of a `portion of the surface dirt whichis taken from the road by the action of the Scrapers andinoved in thedirection of the middle ot the-road vwhere `smoothed to `forni a crown.

it is Vmentioned patent a wheeled frame isshown the rearwardlyconvergent to support In Patent No. 1,133,876' the scraper bars.

wheel supported carrying frame isomittcd.

It is to bev understood, however, .that the present invention is equally`applicable to i the two types of machines.

the machine.

In machines of the general type shown inthe above mentioned patents thedirt displaced by the scra-perbars and issuing' therebetween requires tobe smoothed and compacted, and to this end it is not uncommon to utilizedrags which have either been operated independently or connected withIttrequentlyY happens, however, that the Asurface dirt is displaced bythe Vscraper bars in such quantities as to render it impossible foramere drag having 1 a'ti'oweling action to distribute such dirt properly,the result beingithat a distinct ridge of excessive height would beformed at the crown of the road. The 'present invention has for itsobject to produce a simple and improved spreading device, particularlyadapted to be used in connection with mai cliines of the type referredtO,-,and by the .action ofwhich the dirt issuing between the scraperbars will bespi'ead and redistributed over the. surface ot' theroad,-thns lea-ving the roadin a goodsmooth condition, and f seen inFig.V 1.

A further object vof the invention is to simplify andiniprove theconstructionof the spreaderand also to so construct the same as tovenable the angle between the limbs thereof to be varied. i

`With Vtheseand other endsi-n view which?,

will readily appear as the nature of'the invention is better understood,the same consists in the improved-construction andynovel arrangement andcombination ofparts which will be hereinafter fully described andpartieularly'pointed out in the claims.

Corresponding parts in the several i'igur'es are; denoted byvlikevcharacters of reference. The improved spreader in its-:most sirnple" ffected.

form consists of a plate or bar of steel or 'to reinforce theconstruction.

Under the mcdied construction exemplilied in Fig. 5 the limbs or wings,here desig-v nated by 15', are flexibly connected together by a hingejoint 19 including a pintle 20 having an eye 21 at Vits upper end forconvenience in connecting the spreader with the road machine. The wings15 are adjustably connected together by means of a cross bar or brace 22which may be provided at `each end with a plurality of perfor-ations 225with which the wings may be adjustably connected by means of bolts 2l.Any other well known means may, however, be adopted forV adjustablyyspacing and connecting the wings 15.Y

25, 25 represent the scraper bars of a frameless road machine, thestructure of said machine being illustrated in Fig. 1 of'Letters Patent,No. 1,133,876, previously referred to. |The scraper bars are connectedtogether and spaced apart near their rear ends by means of a cross bar26, the connection of which with the scraper bars is of such a nature asto allow the latter to move independently. YOn the cross bar 26 ismounted an upright 2T having a plurality of apertures 28 for thereception of an eye bolt 29, the eye of which may be engaged orconnected with the eye 16 of the spreader, shown in Fig. 4, or with theeye 2l associ- `ated with the spreader shown in F ig. 5.

The spreader may thus be loosely connected with the cross bar 2G formovement in a horizontal plane and also with freedom for movement of therear ends of the wings of the spreader in a vertical plane, while bychanging the eye bolt 29 from one to another of the apertures 28,vertical adjustment of the nose of the spreader may be ef- Under themodification shown in Fig. 2 the V-shaped spreader is connected with thecross bar 26 adjacent to the ends thereof by means of flexible elementssuch as chains 30, the rearward ends ofy said chains being connectedwith the wings of the spreader. In this figure the form of spreaderillustrated in Fig. l is shown, but it is obvious that the constructionof the spreader used in this connection may be modified.

`When the spreader is applied to and used in connection with a roadmachine of the type shown in Letters Patent No. 1,131,409, the drag ortroweling device shown in said dom of lateral and vertical movement.

'illustrated in Fig. o

patent is dispensed with, but the lifting device including a suitablyguided chain 31 and a drum shaft 32 is retained.` The spreader which maybe of the type shown in Fig. l1 is connected with the cross bar 33spacing the rear ends of the scraper bars by means of chains 31, and thecross bar 18 of the spreader is connected with the chain 31 ofthelifting device, said chain being shown as being terminally bifurcatedand connected with the cross bar 18near the ends of the latter. t

It is desired to be understood that while Vthe spreader has been shownas applied to two particular forms'of road machines, there are manyother patterns of machines in connection with which it may beadvantageously used. It is, furthermore, to be understood that nolimitation is made either to the particular form or construction of thelspreader or to the manner of connecting the said spreader with the roadmachine, except that the connection must be such as to permit thespreader to have the necessary free- 1n the operation of the device thespreader 90 engages the dirt displaced by the scraping device of theroad machine, and it operates to redistribute such dirt over the surfaceof the road. By raising or lowering the point of attachment of the noseof the spreader, the height of the crown formed on the road may bevaried. When the form of spreader is employed', the angle between thelimbs of saidA spreader may be 100 varied, and by so doing the dirt maybe distributedover a greater or lesser area.V

Having thus described the invention, what is claimed as new, is2- l 1.The combination with a road machine having rearwardly convergentscrapers and a cross bar connecting and spacing the same at their rearends for `the passage of dirt therebetween, of a V-shaped spreaderhaving ground engaging` limbs, and means whereby the nose of thespreader is flexibly connected with the cross bar to give the body ofthe spreader freedom for Vertical and lateral movement, the nose of thespreader being restricted from such movement. Y

2. The combination with a road machine having rearwardly convergentScrapers and a cross bar connecting the same and spacing them apart attheir rear ends for the passage of dirt therebetween, of a V-shapedspreader having ground engaging limbs and means including interengagingeyes whereby the nose of the spreader is connected with the cross bar.

3. The combination with a` road machine having rearwardly convergentscrapers and a cross bar connecting said Scrapers and spacing them apartat their rear ends for the passage of dirt therebetween, of a V- 130shaped spreader ileXibly connected therewith, said spreader havingground engaging limbs, and hoisting means mounted on said frame wherebythe rearward end portions of the spreader limbs may be lifted clear ofthe ground.

4. The combination with a road machine having rearwardly convergentScrapers and a cross bar connecting and spacing the same apart at theirrear ends, of an upright mounted on said cross bar, a V-shaped spreader,and means for connecting-the nose of the spreaderl flexibly andadjustably with the upright at various elevations and with f freedom forswinging movement in .vertical` and lateral planes.

5. The combination with a road machine having rearwardly convergentScrapers and a cross bar spacing and connecting the same lat their yrearends, of a V-shaped 20 pintle having an eye, an eye on the cross 25 barwith which the eye of the pintle is engaged, and means whereby the limbsof the spreader are adjustably connected to vary the anglertherebetween. v

In testimony whereof we alx our signa- 30 tures in presence of twowitnesses.
